FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes a kinesin family member 1 binding protein that is characterized by two tetratrico peptide repeats. The encoded protein localizes to the mitochondria and may be involved in regulating transport of the mitochondria. Mutations in this gene are associated with Goldberg-Shprintzen megacolon syndrome.

Knockout affects innervation of the digestive tract, and the development of the olfactory bulb and the anterior commissure in the brain. [provided by MGI curators]
